The present utility model will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the utility model and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the utility model.

The utility model provides a quick core-changing die-cutting die which is suitable for die-cutting raw material plates to obtain die-cutting application scenes of required workpieces, and can effectively solve the problem that the existing die-cutting die cannot be compatible with workpieces of various specifications.

Referring to fig. 1, in the present embodiment, a rapid core changing die cutting die includes an upper die assembly 1 and a lower die assembly 2.

Wherein, referring to fig. 2, the upper die assembly 1 comprises an upper die frame 101 provided with an upper accommodating cavity 1011, a punch assembly 102 detachably mounted in the upper accommodating cavity 1011, and an upper die top plate 103 fixedly mounted above both the upper die frame 101 and the punch assembly 102 by a fastener.

Referring to fig. 3, the lower die assembly 2 includes a lower die frame 201 provided with a lower receiving cavity 2011, a blanking plate group 202 detachably mounted in the lower receiving cavity 2011, and a lower die bottom plate 203 fastened and mounted under both the lower die frame 201 and the blanking plate group 202 by fasteners.

In this embodiment, the punch assembly 102 includes a punch fixing plate 1021 located in the upper housing cavity 1011 and a punch body 1022 protruding below the punch fixing plate 1021; correspondingly, the blanking plate group 202 is provided with a blanking insert 2021 corresponding to the position of each punch body 1022, and the blanking insert 2021 is provided with a blanking hole 2021a for the punch body 1022 to pass through.

When the workpiece is needed to be die-cut, the raw material plate 4 is placed on the blanking plate group 202, then the upper die assembly 1 is driven to be towards the lower die assembly 2 for die assembly, and the punch body 1022 can punch the corresponding position on the raw material plate 4 into the blanking hole 2021a, so that the needed workpiece is obtained;

when the specification of the required workpiece changes, only the new punch assembly 102 and blanking plate group 202 need to be replaced, and the upper die top plate 103, the upper die frame 101, the lower die bottom plate 203, the lower die frame 201 and the like can be reused;

therefore, the quick core-changing die-cutting die provided by the embodiment can be compatible with workpieces of various specifications, and when workpieces of different specifications are produced, only the punch assembly 102 and the blanking plate group 202 need to be replaced, other components can be reused, and the cost is low.

In this embodiment, the upper die frame 101 is connected to the punch fixing plate 1021 through an i-shaped positioning block 104, so as to achieve the relative positioning between the upper die frame 101 and the punch fixing plate 1021.

Specifically, a plurality of outer T-shaped grooves 1012 are provided at the edge of the upper housing cavity 1011, and an inner T-shaped groove 1021a is provided at the position of the punch fixing plate 1021 corresponding to each of the outer T-shaped grooves 1012;

the outer T-shaped slot 1012 and the corresponding inner T-shaped slot 1021a are aligned to form an i-shaped slot into which the i-shaped positioning block 104 is inserted.

It should be noted that, in theory, the size of the upper housing cavity 1011 should be the same as the punch fixing plate 1021 so that the punch fixing plate 1021 does not shake laterally after the punch fixing plate 1021 is put into the upper housing cavity 1011. However, if the upper housing cavity 1011 is larger in size, the processing time is long if the upper housing cavity 1011 is processed by using a device with higher precision, in order to shorten the processing time, the upper housing cavity 1011 is often processed by using a device with lower precision, so that the obtained upper housing cavity 1011 is larger in size, in order to avoid the transverse shaking of the punch fixing plate 1021 in the upper housing cavity 1011, some I-shaped grooves with smaller size but higher precision can be processed, and after the I-shaped positioning blocks 104 are placed in the I-shaped grooves, the transverse shaking of the punch fixing plate 1021 in the upper housing cavity 1011 can be avoided, and the I-shaped grooves are smaller in size, so that the required processing time is less, and the influence on the production efficiency is not great.

In this embodiment, the lower die carrier 201 is also connected to the blanking plate set 202 through the i-shaped positioning block 104, and the specific connection manner of the two is similar to that of the upper die carrier 101 and the punch assembly 102, so that description thereof will not be repeated.

Optionally, a vertical sleeve 301 protruding downward is fixedly arranged on the upper die top plate 103, and a vertical guide post 302 protruding upward is fixedly arranged on the lower die bottom plate 203; the vertical guide post 302 is inserted into the vertical sleeve 301 and is slidably connected with the vertical sleeve 301; the buffer spring 303 is sleeved on the vertical guide post 302.

When the upper die assembly 1 and the lower die assembly 2 are assembled, the vertical guide posts 302 are gradually inserted into the vertical sleeves 301, the vertical sleeves 301 gradually press the buffer springs 303 downwards, the buffer springs 303 provide certain elastic buffer, and the damage to the quick core-changing die-cutting die due to overlarge impact force when the upper die assembly 1 and the lower die assembly 2 are assembled is avoided.

The quick core-changing die-cutting die provided by the embodiment has the following advantages:

(1) when the specification of the required workpiece changes, only the new punch assembly 102 and blanking plate group 202 need to be replaced, and the upper die top plate 103, the upper die frame 101, the lower die bottom plate 203, the lower die frame 201 and the like can be reused;

(2) the upper die carrier 101 and the punch fixing plate 1021 are connected by using the I-shaped positioning block 104, and the positioning precision and the production efficiency are both considered.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present utility model, and they are not intended to limit the scope of the present utility model, and all equivalent embodiments or modifications that do not depart from the spirit of the present utility model should be included in the scope of the present utility model.
